Ah, I see. Stainless will work then, but do be aware of the line resistance issue. I'd hate for you to drop a lot of money on stainless tubing and it give you a bad pour because your lines are too short.
If I were in your shoes, I'd get on the phone to Birdman, Farmhouse, or one of the others that carry accuflex and see if they can hook you up with some by Friday. I bet it'd be cheaper than stainless, and you'd be happier in the long run.
